Ten Questions and Answers about Mobile Phone Radiation Ten Questions and Answers about Mobile Phone Radiation [pic] | ||Mobile phone radiation has always been a topic of concern to people, especially those working in the white-collar class, who use mobile phones at a much higher frequency than other groups. The Institute of Telecommunications Transmission (China Telecommunication Technology Laboratory) is a specialized institution in my country that tests the transmission quality of telecommunications products. Engineer Ma Xin has done a lot of research on the radiation of telecommunications products. He answered questions about mobile phone radiation. ||1. Can anti-magnetic stickers really prevent radiation? Not very ideal, and to be more serious, it doesn\'t work at all. Because the radiation source is the mobile phone antenna, and the so-called anti-magnetic sticker is attached to the listening device, how can it work? What if the anti-magnetic sticker is attached to the antenna? Absolutely not, because this will change the magnetic field around the antenna, causing the antenna signal to change, making the call not normal. ||2. When is the radiation value of the mobile phone the highest? When the mobile phone signal is just connected, because at this time the signal transmission system is not stable and is at the maximum working function rate. Therefore, when consumers are using their mobile phones, it is best to place the phone farther away from the head at the moment the signal is connected. 3. Is there any difference in radiation between mobile phones using the CDMA and GSM systems? The radiation levels of mobile phones of different standards are different. The radiation standard for mobile phones using the GSM standard is 0.6 to 2 watts, while the radiation standard for mobile phones using CDMA technology is much smaller, so CDMA mobile phones are called green mobile phones. ||4. Is there any difference in radiation when mobile phones operate at frequencies of 900/1800 Hz respectively? || According to the characteristics of electromagnetic waves, the higher the operating frequency, the weaker its penetration, so when a mobile phone operates at 1800 Hz, its radiation is relatively weak. ||5. Can mobile phone headphones also serve as antennas? No, because the copper wire material of the headphones is different from that of the antenna, and the antenna is also made during the manufacturing process...
